High Precision Swiss Screw Machining/CNC Machining & Grinding Services

For specialized, high precision parts where tight tolerances are important, IFG Instruments provides CNC Swiss screw machining services as well as standard CNC machining and grinding. Swiss screw machining is ideal for smaller scale parts where several machining operations may be required, and we are equipped to work with parts with diameters from 0.20 mm to 16 mm (0.008” to 0.640”), up to 180 mm (7.0”) long. For our standard (non-Swiss) CNC grinding and machining operations, we can handle parts from 0.20 mm to 30mm (0.008” to 1.20”) in diameter and a 180 mm (7.0”) length.

Our Swiss screw machines feature a collet and guide bushing system that keeps parts vibration-free as they are being worked, allowing us to achieve a fine level of detail in our operations. Our machining methods also allow us work with conventional as well as a wide range of exotic metals, including Nivapoint. Swiss and conventionally machined products are used in instruments and apparatus such as water pivots, pinion applications, and helical or spur gears with fine pitches.

The Corepoint strengths are almost constant in the temperature range

-58 °F to 842 °F
(-50 °C to 450 °C)

Corrosion Stability

Corrosion proof against all acids. Except moderate to high corrosion by aqua regia (HCL+ HNO3) 3:1, hydrofluoric acid (HF), caustic hydrate of soda (NAOH) and caustic potash (KHO) to 370° C, sulphuric above 50% over 60 °C, bromine.

Welding & Brazing

Use Castolin 197 with binder 159 A for brazing. For an absolutely corrosinresistant brazed joint precious metal brazing solders with melting points around 1100 °C will give best results.


Corepoint - parts are being manufactured up to a maximum diameter of 1.5 mm (.059").
